Description

Title of the invention: Method and device for controlling a vehicle display system comprising a blind spot monitoring system and a digital rearview system Technical field

[0001] The invention relates to methods and devices for controlling a display system of a vehicle, in particular but not exclusively a motor vehicle. The invention relates in particular to a method and a device for controlling the display of graphic content relating to a blind spot monitoring system, known as a BSM (Blind Spot Monitoring) system, and / or graphic content relating to a digital rearview system, known as an RNE (Exterior Digital Rearview) system, of a vehicle. The invention also relates to a method and a device for assisting the driving of a vehicle. Technological background

[0002] Some contemporary vehicles have several screens on board to display information useful to the driver for driving the vehicle as well as comfort information, such as, for example, information for interacting with the infotainment system, also called the IVI system (from the English "In-Vehicle Infotainment" or in French "Infodivertissement monté"), of the vehicle.

[0003] Among these screens, it is known to incorporate one or more LCD (Liquid Crystal Display) type screens, for example TFT (Thin-Film Transistor) type, or OLED (Organic Light-Emitting Diode) type.

[0004] Certain vehicles equipped with a digital rearview system, known as an RNE system, comprise, for example, a multitude of display screens integrated into the dashboard and / or into the trim of the front doors of the vehicle to display both the images received from the exterior side cameras of the RNE system and also all of the information and HMI (Human-Machine Interface) content necessary for controlling the vehicle.

[0005] The multiplication of systems embedded in the vehicle and the multiplication of means of command or control of these systems lead to a complexity of 1THM by which a user interacts with the embedded systems to control them, with in particular a multiplication of icons, messages displayed or command shortcuts whose control and management are consequently complicated. for a user. The user experience may be degraded and the attention of the vehicle driver may be reduced when different messages are displayed on the on-board screen(s).

[0006] Furthermore, the multiplication of display screens on board a vehicle as well as the variety of means of command and control of the on-board systems of the vehicle increase the price of the vehicle. Summary of the present invention

[0007] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0008] Another object of the present invention is, for example, to improve the user experience with respect to a blind spot monitoring system and / or a digital rear vision system of a vehicle.

[0009] According to a first aspect, the present invention relates to a method for controlling a display system of a vehicle, the vehicle having a blind spot monitoring system, called a BSM system, and a digital rearview system, called a RNE system, the display system comprising a touch screen, the method being implemented by at least one processor, the method comprising the following steps: - reception of first data representative of a command to display a signaling indicator representative of the BSM system; - control of display of the signaling indicator in a determined content of a human-machine interface, called HMI, displayed in a first zone of the touch screen following reception of the first data; - reception of second data representative of a type of a first tactile press on the indicator light; - control of display of a first graphic content or of a second graphic content in at least a second zone of the touch screen different from the first zone according to the second data, the first graphic content being representative of an activation state of the BSM system and the second graphic content being representative of at least one image obtained from at least one camera of the RNE system.

[0010] The direct use of the indicator light representative of the BSM system to request the display of a first graphic content associated with the BSM system or a second graphic content associated with the RNE system allows the driver to obtain additional information or content on demand, by simply touching the indicator light. The display control of the first graphic content and the display control of the second graphic content are both carried out via the indicator light, which reduces the control means necessary for controlling these two systems. All of the content is also displayed on a single screen, which promotes access to information and minimizes the time spent searching for information. This improves driver alertness, as well as the safety of the vehicle and its passengers.

[0011] Centralizing the controls on a single screen also eliminates the need for physical buttons to control the BSM system and the RNE system, thereby reducing vehicle design and manufacturing costs.

[0012] According to a variant, the first graphic content is displayed when the second data is representative of a first short tactile press of a duration less than a threshold, and the second graphic content is displayed when the second data is representative of a first long touch press lasting longer than the threshold.

[0013] According to another variant, when the activation state of the BSM system corresponds to an active state, the first data are representative of the active state of the BSM system, and when the activation state of the BSM system corresponds to an inactive state, the first data are representative of a turn signal activation command on one side of the vehicle.

[0014] According to another variant, the first graphic content comprises: - a first graphical object indicative of a current activation state of the BSM system; - a second graphical object configured to control a modification of the current activation state of the BSM system by touching the second graphical object; and - a third graphical object configured to control a set of parameters of the BSM system by touching the third graphical object.

[0015] According to an additional variant, the second graphic content is furthermore a function of third data representing activation of the vehicle's turn signals on a determined side of the vehicle, at least one image being representative: - a right side view of the vehicle when the third data is representative of activation of turn signals on the right side of the vehicle; and - a left side view of the vehicle when the third data is representative of activation of turn signals on the left side of the vehicle.

[0016] According to another variant, the method further comprises the following steps: - reception of fourth data representative of a tactile press on the at least one image; - display control of a third graphic content comprising a set of fourth graphic objects configured to control a set of parameters of the RNE system by touch pressure on at least one fourth graphic object of the set of fourth graphic objects.

[0017] According to an additional variant, the method further comprises the following steps: - receiving fifth data representative of a press on the touch screen outside a display area of the third graphic content; - control of end of display of the third graphic content following reception of the fifth data.

[0018] According to another variant, the method further comprises the following steps: - reception of sixth data representative of a second long tactile press of duration greater than the threshold on the indicator light; - control of end of display of the second graphic content following the reception of the sixth data.

[0019] According to a second aspect, the present invention relates to a device for controlling a display system of a vehicle, the device comprising a memory associated with a processor configured for implementing the steps of the method according to the first aspect of the present invention.

[0020] According to a third aspect, the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention or a system as described above according to the third aspect of the present invention.

[0021] According to a fourth aspect, the present invention relates to a computer program which comprises instructions adapted for executing the steps of the method according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0022] Such a computer program may use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0023] According to a fifth aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the method according to the first aspect of the present invention.

[0024] On the one hand, the recording medium may be any entity or device capable of storing the program. For example, the medium may comprise a storage means, such as a ROM memory, a CD-ROM or a microelectronic circuit type ROM memory, or even a magnetic recording means or a hard disk.

[0025] On the other hand, this recording medium may also be a transmissible medium such as an electrical or optical signal, such a signal being able to be conveyed via an electrical or optical cable, by conventional or terrestrial radio or by laser beam. self-directed or by other means. The computer program according to the present invention can in particular be downloaded from a network such as the Internet.

[0026] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to perform or to be used in performing the method in question. Brief description of the figures

[0037] A method and device for controlling a display system of a vehicle will now be described in the following with reference to Figures 1 to 9. The same elements are identified with the same reference signs throughout the description which follows.

[0038] The terms "first(s)", "second(s)" (or "first(s)", "second(s)"), etc. are used in this document by arbitrary convention to enable different elements (such as operations, means, etc.) implemented in the embodiments described below to be identified and distinguished. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0039] According to a particular and non-limiting example of embodiment of the present invention, the control of a display system on board a vehicle is for example implemented by one or more computers of the vehicle, for example via one or more processors.

[0040] For this purpose, the display of a signaling indicator representative of a BSM system is controlled so that this signaling indicator is displayed in a determined content of a human-machine interface, called HMI, displayed in a first zone of a touch screen of the vehicle display system. The signaling indicator corresponds for example to a symbol or a pictogram representing the BSM system. The signaling indicator is displayed following the reception of first data representative of a command or request to display the signaling indicator. The first data are thus representative of an activation state of the BSM system corresponding to the active or activated state of the BSM system, or, when the BSM system is in the inactive state, the first data correspond to data for activating turn signals on one side of the vehicle, the activation of the turn signals being for example initiated by the driver of the vehicle via an ad hoc control member.

[0041] Second data representative of a first touch press on the indicator light, and more particularly of the type of the first touch press, are received from the touch interface, for example when a user makes a touch press on the touch screen at the location where the indicator light is displayed. The first touch press is thus for example of the short (or brief) type or of the long type.

[0042] Following the reception of the second data, the computer controls the display of a first graphic content or a second graphic content according to the type of the first touch press. The first graphic content is representative of an activation state of the BSM system and the second graphic content is representative of at least one image obtained from at least one camera of the digital rear vision system of the vehicle, called RNE system.

[0043] Such a method makes it possible to control, via a voluntary action, the display of a set of graphic contents relating to the BSM system or to the RNE system.

[0044] [Fig.l] schematically illustrates a part of the passenger compartment of a vehicle 10, according to a particular and non-limiting example of embodiment of the present invention.

[0045] The vehicle 10 corresponds for example to a vehicle with a thermal engine, with electric motor(s) or even a hybrid vehicle with a thermal engine and one or more electric motors. The vehicle 10 thus corresponds for example to a land vehicle, for example an automobile, a truck, a bus.

[0046] The vehicle 10 advantageously incorporates a display system comprising a screen 13 with a touch interface and a computer configured to control the display of content(s) of a graphical MMI on the touch screen 13. The computer corresponds for example to the computer of the infotainment system, called the IVI computer (from the English “In-Vehicle Infotainment” or in French “Infodivertissement embargo”) of the vehicle 10.

[0047] The touch screen 13 corresponds for example to a screen of the LCD type (from the English “Liquid Crystal Display” or in French “Display à cristals liquide”), for example of the TFT type (from the English “Thin-Film Transistor” or in French “Transistor en film mince”), or OLED type (from the English “Organic Light-Emitting Diode” or in French “Diode électroluminescente biologique”).

[0048] The touch screen 13 is configured to display content intended for the driver and passengers of the vehicle 10. The touch screen 13 is also configured to allow the driver and / or passengers of the vehicle to interact with one or more systems embedded in the vehicle via a human machine interface (HMI) displayed on the touch screen 13. For example, the screen 13 is configured to interact with the IVI system and / or a blind spot monitoring system, called a BSM system and / or a digital rearview system, called a BSM system.

[0049] The screen 13 is for example arranged in the dashboard 11, in a space provided behind the steering wheel 14 according to the point of view of a driver of the vehicle 10 seated in the driver's seat 15. Such a screen 13 is also called the instrument panel or dashboard of the vehicle 10.

[0050] According to a particular embodiment, the display system comprises one or more other screens, for example a screen of a so-called head-up display device or system corresponding for example to a transparent or semi-transparent blade arranged in such a way that a driver seated in the seat 15 sees the content displayed or projected on the transparent blade when the driver drives the vehicle 10. The display system further comprises for example a display screen 12 arranged in a central space of the dashboard 11.

[0051] According to a particular embodiment, the vehicle 10 carries one or more on-board systems each controlled by one or more computers, in particular a BSM system and an RNE system. These computers, with the IVI computer, form for example a multiplexed architecture for the realization of different services. useful for the proper operation of the vehicle and to assist the driver and / or passengers of the vehicle in controlling the vehicle 10 via the control of the system(s) embedded in the vehicle 10. The computers communicate and exchange data with each other via one or more computer buses, for example a communication bus of the CAN (Controller Area Network) type, CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to the ISO 17458 standard), LIN (Local Interconnect Network) or Ethernet (according to the ISO / IEC 802-3 standard).

[0052] The vehicle 10 thus advantageously incorporates a blind spot monitoring system, known as a BSM system. Such a system is also called a blind spot warning system, known as BLIS (from the English “Blind spot Information System” or in French “dead spot information system”) or blind spot detection system. Such a system makes it possible to alert the driver of a vehicle of the presence of another vehicle located in a blind spot, this other vehicle not being visible from the exterior rearview mirrors of the vehicle since it is located in a blind spot. The alert generally takes the form of a warning light arranged in the mirror of each exterior rearview mirror which is illuminated when the presence of the other vehicle is detected in the blind spot.The detection of a vehicle in the blind spot on the left or on the right of the vehicle 10 is for example obtained from data received from an object detection sensor such as a radar or a sonar arranged for example on the rear left corner, respectively right, of the vehicle 10. According to a variant, each object detection sensor used for the detection of a vehicle in a blind spot corresponds to a camera, for example arranged on each exterior side mirror of the vehicle 10, the lens of each camera being directed towards the rear of the vehicle 10 according to the direction of travel of the vehicle 10. A blind spot of the vehicle 10 corresponds to a masked area of the field of vision of the driver of the vehicle 10 obtained via the rearview mirrors (interior and exterior) of the vehicle 10, that is to say an area that the driver cannot see in the exterior and / or interior mirrors of the vehicle 10.

[0053] The vehicle 10 also has a digital rearview system, called the RNE system. A digital rearview system corresponds to a system in which each conventional exterior side mirror-type rearview mirror is replaced by a camera associated with a screen configured to display the images acquired by the camera. Each exterior side camera is for example arranged outside the vehicle in place of the mirror-type rearview mirror and is directed towards the rear of the vehicle to obtain a left side view (via the left camera) and a right side view (via the right camera) of vehicle 10.

[0054] According to an alternative embodiment, the digital rearview system complements the mirror-type exterior side mirrors, without replacing them. According to this variant, each mirror-type exterior side mirror (i.e. the left exterior side mirror and the right exterior side mirror) is equipped with a camera whose lens is directed towards the rear of the vehicle 10. The images acquired by each camera (left and right) are transmitted to a computer controlling one or more screens of the vehicle for display on this or these screens.For example, the images obtained from the left camera are displayed on a left screen in an area of the passenger compartment of the vehicle 10 on the left side of the passenger compartment and the images obtained from the right camera are displayed on a right screen in an area of the passenger compartment of the vehicle 10 on the right side of the passenger compartment, each screen (left and right) being visible to the driver seated in the driver's seat 15. According to a variant, the computer controlling the display of the images obtained from the cameras of the RNE system is further configured to control the display of these images on the screen 13 (or on any other screen such as the screen 12), as explained in more detail below. According to this variant, the display of the images on the screen 13 complements the display of the images on the left and right screens provided for this purpose or replaces the display of the images on the left and right screens, the passenger compartment of the vehicle 10 then not comprising such left and right screens.

[0055] A process for controlling a display system on board the vehicle 10 is advantageously implemented by one or more processors of the display system, for example by one or more processors of one or more computers, for example the computer of the IVI system.

[0056] In a first operation of the process, first data representative of a command or a request to display a signaling indicator representative of the BSM system are received.

[0057] These first data correspond for example to: - first activation data of the blind spot monitoring function, i.e. first data representative of the active or activated state of the BSM system: when the BSM system is controlled to switch to the active state (for example by default when starting the vehicle 10 or via a command from the driver via an HMI (human-machine interface) of the vehicle 10 allowing the activation and deactivation of the BSM system to be controlled, the BSM system via its computer transmits the first data to the computer in charge of the process, for example the IVI computer, so that the latter triggers the display of the warning light on the screen, for example on the screen 12 or the screen 13; or - first data representative of a command to activate the indicators on one side of the vehicle 10, the indicators being activated by a command from the driver to, for example, signal a change of direction or a change of lane: the computer controlling the indicators of the vehicle 10 transmits the first data to the computer in charge of the process, for example the IVI computer, so that the latter triggers the display of the signaling indicator on the screen, for example on the screen 12 or the screen 13, as well as a pictogram or indicator representing the activation of the indicators (for example a flashing arrow oriented towards the side corresponding to the side of activation of the indicators).

[0058] In a second operation of the process, the display of the indicator light representative of the BSM system of the vehicle 10 is controlled in such a way that the indicator light is displayed on the touch screen 13 in a determined content of a human-machine interface, called HMI, which content is displayed on the touch screen 13, following the reception of the first data.

[0059] The displayed content comprises, for example, a set of information useful to the driver to ensure control and supervision of the vehicle 10. The set of information comprises, for example, the instantaneous speed of the vehicle 10 when the latter is in a rolling or traffic phase, i.e. in motion, driven by the engine of the vehicle 10, a rev counter, for example the remaining autonomy (expressed for example in km), the distance traveled, a volume or level of fuel remaining in the tank, etc.

[0060] [Fig.2] illustrates a result of the display control of the signaling indicator 21 on the touch screen 13, according to a particular and non-limiting exemplary embodiment.

[0061] The signaling indicator 21 corresponds for example to a pictogram representing a first vehicle emitting a radar signal (corresponding to the vehicle 10) on the left side of this first vehicle and detecting a second vehicle located to the left of the first vehicle behind the first vehicle.

[0062] A witness 22 is also shown in [Fig.2], this witness 22 illustrating the activation of the left turn signals of the vehicle 10, this witness 22 only being displayed when the driver has commanded the activation of the left turn signals.

[0063] This indicator 22 is thus not always displayed, only indicator 21 being for example displayed when the display of indicator 21 is triggered by the active state of the BSM system (unless the driver requests activation of the indicators to signal a change of direction).

[0064] When the display of the indicator 21 is triggered by the active state of the BSM system (blind spot monitoring function activated), the signal indicator 21 is displayed as long as the BSM system is in the active state.

[0065] When the display of the indicator 21 is triggered by the activation of the indicators, the signaling indicator 21 is displayed for a determined duration (the start of which corresponds to the moment of activation of the indicators), for example for 5 or 10 seconds. According to a variant, the indicator light 21 is displayed as long as the indicator light 22 representing the active state of the indicators remains displayed on the screen 13.

[0066] A display control of a signaling indicator, of graphic content or of any graphic object (text, pictogram, icon, etc.) comprises a rendering of the graphic content or of the graphic object, such rendering corresponding to a set of operations carried out by one or more processors on the pixels of one or more images of the graphic content to be displayed on the screen 13. For example, the rendering consists of associating with a set of pixels of an image pixel data (for example color data expressed in an RGB type space (from the English "Red, Green, Blue" or in French "rouge, vert, bleu")) associated with each graphic object.

[0067] The display control of the indicator light 21 thus comprises the transmission of control signals to the touch screen to modify the values associated with the pixels of the touch screen 13 at the location intended to display the indicator light 21 (or any graphic object).

[0068] The display of the indicator light 21 is controlled so that this indicator light 21 is displayed in a first determined zone of the touch screen 13. According to the particular example of [Fig.2], the first zone corresponds to an area located at the bottom left of the screen 13, according to the point of view of a person looking at the screen 13 from the driver's seat 15 of the vehicle 10 for example.

[0069] In a third operation, second data representative of a first tactile press 201 on the indicator light 21 are received, following a tactile press 201 of a user (for example the driver of the vehicle 10) on the indicator light 21.

[0070] A tactile press on the indicator light 21 sends information to the IVI computer so that the latter implements one or more functions associated with the command corresponding to the tactile press.

[0071] The second data representative of the touch pressure are for example received via one or more data buses connecting the touch interface of the screen (or a computer controlling such a touch interface where appropriate) and the IVI computer.

[0072] The second data are for example more precisely representative of the type of the first tactile press 201, the first tactile press being of the type: - short or brief, that is to say a tactile press whose duration of press on the indicator 21 is less than a threshold duration (for example equal to 500 or 1000 ms); or - long, that is to say a tactile press whose duration of pressing on the indicator 21 is greater than the threshold duration.

[0073] According to a variant, an additional type corresponds to a double click, i.e. a sequence of two consecutive and close touch presses (for example, with less than 250 or 500 ms between the two consecutive touch presses).

[0074] In a fourth operation of the process, the IVI computer controls the display of graphic content in at least a second zone of the touch screen 13 different from the first zone comprising the indicator 21, the control of display of the graphic content being triggered by the reception of the second data.

[0075] The displayed graphic content corresponds to a first graphic content or to a second graphic content depending on the second data, according to the type of the first touch press 201 indicated in the second data.

[0076] The first graphical content comprises information representative of the activation state of the BSM system and the second graphical content is representative of one or more images obtained from at least one camera of the RNE system. Each image contained in the second graphical content is representative of an exterior side view of the vehicle 10, i.e. a left side view obtained from the left camera of the RNE system or a right side view obtained from the right camera of the RNE system.

[0077] The fourth operation comprises for example the transmission of a request by the IVI computer to the computer controlling the BSM system and / or the transmission of a request by the IVI computer to the computer controlling the RNE system, via one or more data buses, to receive the information(s) necessary for the display of the first graphic content or the second graphic content, depending on the type of the first touch press 201.

[0078] [Fig. 3] illustrates the result of the display of a first graphic content 30 according to a particular embodiment example, the first graphic content being displayed under the control of the computer in charge of the process when the second data are representative of a first short or brief tactile press 201 on the indicator light 21.

[0079] According to a particular example, the first graphic content 30 is displayed in a window occupying a part of the display area of the screen 13 and corresponding to the second area, this window corresponding for example to a contextual window, also called an intrusive or pop-up window (from the English "pop-up window"). This window is for example displayed next to the first area comprising the indicator 21, for example centered on the screen (around the center of the screen 13).

[0080] The first graphic content 30 illustrated in [Fig.3] comprises: - a first graphic object 31 indicative of a current activation state of the BSM system, i.e. the activation state at the time of the first touch press 201: the first graphic object comprises, for example, text indicating the current activation state (active / activated or inactive / inactivated) of the BSM system and / or an icon or a peak diagram illustrating the current activation state; a first display color is for example associated with the active state (for example blue or green color) and a second display color is associated with the inactive state (for example red or orange color); - a second graphical object 32 configured to control a modification of the current activation state of the BSM system by touch pressure 301 on the second graphical object 32: the second graphical object corresponds for example to a radio button or a check box making it possible to command or control the transition of the BSM system to the inactive state when the current state corresponds to the active state, and conversely to command or control the transition of the BSM system to the active state when the current state corresponds to the inactive state; the second graphical object comprises for example further associated with the radio button to specify or specify the parameter or the function (i.e. the monitoring of the blind spot) controlled by the radio button;and - a third graphic object 33 configured to control a set of parameters of the BSM system by touch 302 on the third graphic object 33: the third graphic object 33 corresponds for example to an icon or a pictogram representing a cogwheel.;

[0081] When the current state of the BSM system is the inactive state, if the driver of the vehicle 10 decides to activate the blind spot monitoring function by switching the BSM system to the active state by tactile pressure 301 on the second graphic object 32, switching the BSM system to the active state causes, for example, the permanent display of the indicator 21 (until the BSM system returns to the inactive state) in the first zone of the screen 13.

[0082] Thus, the first touch press makes it possible to display information associated with the BSM system, each time the driver requests it by a simple touch press on the indicator 21. The first graphic content 30 also makes it possible to simply and quickly access the part of the HMI configured to control the BSM system (activation / deactivation and / or modification of the system parameters) without having to navigate through the different menus and different pages of the HMI of the vehicle 10 associated with the control of the different on-board systems of the vehicle 10.

[0083] In additional operations of the process following the display of the first graphic content 30, data representative of the touch press 302 on the third graphic object 33 are received. This touch press 302 corresponds for example to a short or brief press.

[0084] Receiving the data representative of the touch press triggers the display of a fourth graphic content 40 illustrated in [Fig. 4], the fourth graphic content 40 taking for example the place of the first graphic content 30. According to a variant, the fourth graphic content 40 is displayed next to the first graphic content 30 or in superposition, at least partially, of the first graphic content 30.

[0085] This fourth graphical content 40 comprises a set of graphical objects each configured to adjust a parameter of the BSM system.

[0086] The end of the display of this fourth graphic content 40 is automatically controlled after a determined display duration without tactile action from the driver or any other user with this fourth graphic content 40, for example after 5, 10, 15 seconds of display. According to a variant, the end of the display of the fourth graphic content 40 is implemented when the driver makes a brief tactile press on the screen 13 outside the display area of the fourth graphic content 40.

[0087] In the same way, the end of the display of the first graphic content 30 is controlled automatically after a determined display duration without tactile action from the driver or any other user with this first graphic content 30, for example after 5, 10, 15 seconds of display. According to a variant, the end of the display of the first graphic content 30 is implemented when the driver makes a brief tactile press on the screen 13 outside the display area of the first graphic content 30 or when the driver makes a second brief tactile press on the indicator light 21.

[0088] Figures 5 and 6 each illustrate the result of the display of a second graphic content 50 and 60 according to particular embodiment examples, the second graphic content 50, 60 being displayed under the control of the computer in charge of the process when the second data are representative of a first long tactile press 201 on the indicator light 21.

[0089] According to a particular example, the second graphic content 50, 60 is displayed in a window occupying a part of the display area of the screen 13 and corresponding to a second area different from the first area, the location of the second area varying according to the second graphic content 50 and 60. This window corresponds for example to a contextual window, also called an intrusive or pop-up window (from the English “pop-up window”).

[0090] The display of a second graphic content 50, 60 is controlled as a function of third data representative of activation of turn signals of the vehicle 10 on a determined side of the vehicle 10. Thus, the content of the images included in the second graphic content 50 and in the second graphic content 60 vary according to the side of activation of the turn signals.

[0091] Thus, each image is representative: - of a right side view of the vehicle 10 when the third data is representative of activation of turn signals on the right side of the vehicle 10, as illustrated with [Fig.6] and the second graphic content 60; and - of a left side view of the vehicle 10 when the third data is representative of activation of turn signals on the left side of the vehicle 10, as illustrated with [Fig.5] and the second graphic content 50.

[0092] According to the example of [Fig.5], the second graphic content 50 is displayed on a left part of the screen 13, for example under the indicator light 51 indicating activation of the left turn signals of the vehicle 10.

[0093] This second graphic content 50 is for example displayed superimposed on the graphic content displayed on the screen 13 during the first tactile press 201 made on the indicator 21.

[0094] The images displayed in the second graphic content 50 correspond to the images of the left lateral external environment of the vehicle 10 obtained from the left camera of the RNE system, this left camera being arranged and oriented so as to acquire images of the left side of the vehicle 10, towards the rear of the vehicle 10, these images comprising the blind spot area located to the left of the vehicle 10.

[0095] The display of the second graphic content 50 is triggered by the long tactile press 201 on the indicator 21 and by the activation of the left indicators of the vehicle 10.

[0096] When the display of the indicator light 21 has been triggered by the active state of the BSM system, the display of the second graphic content 50 requires a command to activate the left turn signals of the vehicle 10 to obtain the display of the images of the left view of the vehicle 10.

[0097] When the display of the indicator light 21 has been triggered by the activation command of the left turn signals of the vehicle while the BSM system was in the inactive state, the display of the second graphic content 50 with the display of the images of the left side view of the vehicle 10 is automatic following the long tactile press on the indicator light 21.

[0098] According to the example of [Fig.6], the second graphic content 60 is displayed on a right part of the screen 13, for example under the indicator light 61 indicating activation of the right turn signals of the vehicle 10. This zone in the right part corresponds for example to the symmetrical zone of the zone in the left part receiving the second graphic content 50 relative to the center of the screen 13.

[0099] This second graphic content 60 is for example displayed superimposed on the graphic content displayed on the screen 13 during the first tactile press 201 made on the indicator 21.

[0100] The images displayed in the second graphic content 60 correspond to the images of the right lateral external environment of the vehicle 10 obtained from the right camera of the RNE system, this right camera being arranged and oriented so as to acquire images of the right side of the vehicle 10, towards the rear of the vehicle 10, these images including the blind spot area located to the right of vehicle 10.

[0101] The display of the second graphic content 60 is triggered by the long tactile press 201 on the indicator 21 and by the activation of the right indicators of the vehicle 10.

[0102] When the display of the indicator light 21 has been triggered by the active state of the BSM system, the display of the second graphic content 60 requires a command to activate the right turn signals of the vehicle 10 to obtain the display of the images of the right view of the vehicle 10.

[0103] When the display of the indicator light 21 has been triggered by the activation command of the right turn signals of the vehicle while the BSM system was in the inactive state, the display of the second graphic content 60 with the display of the images of the right side view of the vehicle 10 is automatic following the long tactile press on the indicator light 21.

[0104] The end of the display of the second graphic content 50 or 60 is controlled automatically: the display of the second graphic content 50 or 60 is for example maintained as long as the left or right indicators, respectively, remain activated, the end of the display of the second graphic content 50 or 60 being commanded or controlled with the end of the activation of the left or right indicators, respectively.

[0105] According to an alternative embodiment, the end of the display of the second graphic content 50 or 60 is implemented when the driver makes a second long tactile press on the indicator light 21, the end of the display being triggered by the reception of the data (called sixth data) representative of this second long tactile press on the indicator light 21.

[0106] The digital views displayed in each second graphic content 50, 60 supplement the side views accessible in the left and right side exterior mirrors of the vehicle 10, with different and very useful information during certain life situations (very dense traffic, parking maneuvers, driving at night or in heavy rain, etc.), and this, at the request of the driver.

[0107] The display of these digital images or views on the screen 13 also makes it possible to avoid the need for specific screens for displaying these images.

[0108] In additional operations of the process following the display of the second graphic content 50 or 60, fourth data representative of a touch press on the second graphic content, for example a third touch press 601 on the display area of the second graphic content 60 as illustrated in [Fig.6], are received from the computer in charge of the process. This touch press 601 corresponds for example to a short or brief press.

[0109] Receiving the fourth representative of the touch press triggers the display of a third graphic content 70, as illustrated in [Fig.7].

[0110] This third graphic content advantageously comprises a set of fourth graphical objects configured to control a set of parameters of the RNE system by touching these fourth graphical objects. For example, a determined parameter of the RNE system is associated with each fourth graphical object, a determined parameter being adjusted (or a function activated) via one or more touching touches on the associated fourth graphical object.

[0111] This third graphic content 70 makes it possible, for example, to adjust or configure: - the viewing angle and / or the orientation of each camera of the RNE system; and / or - the overlaying of information on the images obtained from the cameras; and / or - the brightness of the images obtained from the cameras; and / or - the size of the images displayed; and / or - the zoom level (optical or digital).

[0112] The third graphic content 70 is for example displayed in an area adjacent to the second area receiving the second graphic content 40 or 60, for example in an area around the center of the screen 13.

[0113] According to a particular embodiment, the process further comprises the following operations: - reception of fifth data representative of a press on the touch screen 13 outside the display area of the third graphic content 70; - end of display control of the third graphic content 70 following receipt of the fifth data.

[0114] According to a variant of this embodiment, the end of the display of the third graphic content 70 is triggered automatically after a determined display duration (equal to for example 5, 10 or 15 seconds) in the absence of any tactile interaction of a user with this third graphic content 70.
